Definitions

  • the present invention relates to a method and apparatus for automatically feeding lubricating oil to bearing portions of various machine parts.
  • the present invention relates to a method and apparatus for automatically feeding lubricating oil using a microcomputer whereby when a predetermined time for discharging lubricating oil terminates, a discharge mode for a minimum time, for example, for one month, is set to completely discharge the remaining lubricating oil, and the predetermined discharge time is displayed by a display device.
  • Such an automatic lubricating oil feeding apparatus has advantages in that it can continuously feed lubricating oil to places which need the lubricating oil such as bearings without the necessity of a manual feeding operation.
  • the lubricating oil is automatically discharged by a piston which moves downward by a diaphragm.
  • This diaphragm is extended to move the piston by gas pressure provided by an electrochemical reactor.
  • the gas reaction time and the gas pressure of the electrochemical reactor are adjusted by a control circuit, and thus the discharge of lubricating oil can be automatically performed extending from several months to several tens of months.
  • FIG. 1 is a schematic circuit diagram of a conventional lubricating oil feeding apparatus.
  • a plurality of resistors R1 to R5 and a plurality of switches S1 to S5 are connected in series to adjust the current flowing to the electrochemical reactor 20.
  • a display section for visually indicating the operation of the electrochemical reactor 20 is composed of a light-emitting diode LED, driving transistors Q1 to Q3, and resistors.
  • the amount of current applied to the electrochemical reactor 20 is varied in accordance with a specific resistance determined by the on/off state of the switches S1 to S5 to adjust the reaction time of the electrochemical reactor (e.g., gas chamber) 20.
  • the reaction time corresponds to the lubricating oil discharge time, and is extended from one month to several months.
  • the light-emitting diode is turned on to display the operating state of the electrochemical reactor.
  • the electrochemical reaction time is adjusted by controlling the current consumption of the electrochemical reactor and the current consumption is controlled according to the resistance selected by the switches S1 to S5.
  • the conventional apparatus has drawbacks in that the environmental conditions such as the condition inside the bearing portion, the temperature change, etc., cannot be reflected in controlling the lubricating oil discharge time. Further, as time goes by, the internal resistance of the electrochemical reactor (e.g., gas chamber) may vary, causing the current consumption of the reactor also to vary. This causes the proper and accurate discharge of lubricating oil in time and in amount not to be achieved.
  • the electrochemical reactor e.g., gas chamber
  • the predetermined discharge time can be recognized only by checking the on/off state of the switches to cause inconvenience in use. Further, in the event that a portion of the lubricating oil still remains due to the external or internal factors when the predetermined discharge time elapses, a user cannot identify whether or not the amount of the remaining lubricating oil is sufficient for setting of the discharge time again, and thus he can but discard the remaining oil.
  • an automatic lubricating oil feeding apparatus using an electrochemical reactor comprising:
  • a method of automatically feeding lubricating oil using an electrochemical reactor comprising the steps of:
  • FIG. 1 is a schematic circuit diagram of a conventional lubricating oil feeding apparatus.
  • FIG. 2 is a block diagram of the lubricating oil feeding apparatus according to the present invention.
  • FIG. 3 is an algorithm diagram explaining the lubricating oil feeding method according to the present invention.
  • FIG. 4 is a waveform diagram explaining the output control timing according to the present invention.
  • the automatic lubricating oil feeding apparatus includes a microcomputer 10 capable of storing and computing input data and performing an input/output control, a mode switch MS for determining and inputting discharge time data of lubricating oil to the microcomputer 10, a liquid crystal display (LCD) 11 which is driven by an LCD driver 8 provided in the microcomputer 10, a purge driver 12 which is driven by the maximum output of a power driver 6 provided in the microcomputer 10, a driver 13 which is driven by an output of the power driver 6 corresponding to a selected mode, and an electrochemical reactor 20 receiving its operating power supply B* through the purge driver 12 and the driver 13.
  • a microcomputer 10 capable of storing and computing input data and performing an input/output control
  • a mode switch MS for determining and inputting discharge time data of lubricating oil to the microcomputer 10
  • LCD liquid crystal display
  • purge driver 12 which is driven by the maximum output of a power driver 6 provided in the microcomputer
  • a driver 13 which is driven by an output of the power driver 6 corresponding to a
  • the lubricating oil feeding apparatus is properly installed in a required machine parts. If a user manipulates the mode switch MS to select a discharge mode, the microcomputer 10 performs an operating month input mode (step S1 in FIG. 3), for example, for selecting one of 1, 2, 3, 6, and 12-month modes. If it is determined that the selected mode is a purge mode (step S2 in FIG, 3), the microcomputer 10 turns on its output port (step S3 in FIG. 3) to operate the electrochemical reactor 20 with its maximum electrochemical reaction level.
  • the term "on-state of the output port" means a 'LOW' logic level.
  • the output of the power driver 6 is applied to the purge driver 12, and the power supply B* flows to the driver 12 through the electrochemical reactor 20, causing the lubricating oil to be discharged.
  • the microcomputer 10 performs its control operation in accordance with the corresponding input mode.
  • the term "off-state of the output port" means a 'HIGH' logic level.
  • the reaction time of the electrochemical reactor 20 is controlled in such a manner that, in order to control the discharge amount of the lubricating oil, the operating time for each selected mode, i.e., the K time, is determined by the amount of the current consumption of the electrochemical reactor 20, which is obtained by computing an expression IxTM ⁇ TC, where I is the amount of current, TC is a unit time, and TM is the output time according to the selected mode.
  • the K time for each mode is calculated by multiplying Xt by the efficiency of the gas chamber which is converted from the specific resistance value of the gas chamber in accordance with the passed time.
  • step S15 in FIG. 3 the set discharge mode is cleared, and the discharge mode for the minimum time, i.e., for one month, is set under the control of the microcomputer 10 (step S16 in FIG. 3), so that the remaining lubricating oil is completely discharged during the minimum time.
  • the power driver 6 and the driver 13 operate for the one-month mode until the power supply B* being supplied thereto is expired.
  • the set mode is displayed on the LCD as the number of discharge months, and thus a user can easily recognize the discharge months of the present mode.
